It would also be nice if editor preferences were a user meta setting stored in the database and not just stored in local storage as this is right now. Local storage is not very... permanent. Simply changing browsers (or even running the browser in private mode) will cause users to end up in radically different editing experiences without warning. I foresee lots of forum support questions about how to get out of full-screen editor mode and then even more with "why does it keep switching back".
